| 摘 要： | 介绍了目前国外广泛应用的含水层易污染性评价的DRASTIC模型,分析了该模型存在问题及产生原因,讨论了含水层易污染性及其评价中存在的模糊性,建立了多目标模糊模式识别模型,给出含水层易污染性评价大小的习惯性描述语言.分别用DRASTIC模型和多目标模糊模式识别模型对一个应用实例进行了研究,由评价结果的分析比较结果表明,多目标模糊模式识别模型比DRASTIC模型更真实地反映含水层易污染性.

| Abstract: | The DRASTIC,one of the wildly applied systems for aquifer vulnerability evaluation in the world,is introduced and the main problems in it are analyzed.The fuzziness exists in aquifer vulnerability and its assessment are discussed.Then a fuzzy pattern recognition model is presented and the conventional describe language for accessing aquifer vulnerability is suggested.A case study,in which the DRASTIC system and the fuzzy pattern recognition model are applied respectively,is conducted.The results of comparison between the two models show that the fuzzy pattern recognition model is more effective than DRASTIC system. |
